And September goes to find the other humans.
She's very quickly able to find out the known rules and observations, at least.
-Food is free, or at least only at the price of listening. They've never heard of anyone leaving but they don't think eating here is what changes that.
-The library shifts when you're not looking. It behaves more the higher you go. No one knows if there's a top or a bottom or any sides.
-If you go deep, the library stops behaving. Odd people live down there, and some people think there are monsters.
-The library is helpful, at least high up. You'll find the books you need, is the most common thing. The library tries to help people not get lost, and it tries to make sure everyone has bedding and food they like and safety.
-There's debate about whether the library is intelligent, or if it's people subconsciously doing magic to the library, that makes it be helpful.
-People are from different worlds. Some of them have magic other than what the library does for everyone.
-Conflicts between groups of people around here are usually solved by the shelf-witch, who lives on her own and also works as a provider of medicines - reading medicines out of a book is tricky, and you need someone who knows what to do with them.
-They think only people can wander into the library, but some of those people aren't human-shaped. One person swears he saw an orangutan, another a tall, willowy alien with terribly bright eyes. Still, people from similar worlds seem to cluster together - it's mostly humans from Earths, around here.
-Some groups hold enough territory to really have a concept of 'law', but they usually try to signpost the territory they're maintaining. The library is only sometimes helpful about this.
-You need an audience to read items out of a book. Reading to yourself doesn't work. If you listen to a passage for the same stuff a lot, its magic wears thin - food gets bland, medicine less effective, and eventually things stop appearing for you. That's just audience, though, not orator - some people make their living traveling and reading the same stuff to different people.
September gets food and provisions and a little book of provision poems that's gotten all worn out to their ears, but it'll be new to her, and starts making her way back to Rescue.
